Got the three layers torn off today. New shingles go on Tomorrow. What I found in the vaulted area was about 5 inches of space between the roof deck and the sheetrock. There is fiberglass insulation that is less than 2inches thick inside the space.

Is it normal to have 2inches of insulation and 3inches of space between the deck and the sheetrock?

Is it ok to simply blow-in insulation and fill up the rest of the 5in gap? There basically is no venting for this style of roof/ceiling right? I see holes down low under the eves, but up top there’s no outlet(s). Is any air gap needed for venting?
